It is the "Roman Aeronautics Industry" of Bresov.

-In parallel to the Yugoslav IAM, they built the Lorraine 12Eb, the 9-cylinder Gnome-Rhone K9 with 640 CV, the 14-cylinder K14 in the IV-C32 versions with 870 CV for the IAR-37 aircraft, and the III- C36 with 940 CV on the IAR-80 aircraft from 1942.

“IAR-9”

-The 14K (or K14) IIC32 was a Mistral Major and the K14 model 1000A, gave 1,025 CV.

-IAR-6G1 180 CV engines were also made with 6 inline cylinders for the IAR-27 aircraft. They also made a 4-cylinder inline engine. These two were clearly De Havilland license.

-Lastly they made the RR Viper 633-41 with 4,000 lbf of dry thrust and 5,000 lbf with afterburner for the IAR-93 "Orao" aircraft.

-In the 1940's Industria Aeronáutica Romana made the 9-cylinder radial IAR-9 with 650 CV at 4,000 feet of altitude.

From Appendix 6: The illustration below of the 1000-A model engine that gave 1,000 CV is from 1940. It had 14 cylinders in double row and was offered with two types of supercharging, for 12,500 feet and for 10,500 feet.

-In reality the maximum power at take off and climb could reach 1,140 CV.

-The 1000A is a license of the Gnome-Rhone 14K.

“The IAR 1000-A”

-This engine model was pending in the main text.

From Appendix 9: In the main text, a 6-cylinder in line with the reference G-1 is mentioned.

-At the Bucharest Military Museum, one of these engines is exhibited. The picture is taken by E.V., proving it to be an engine with English license of the DH Gipsy Six.

“IAR G1”

“G1 engine plate”

“Unidentified IAR radial engine”

-It is "Industria Aeronautica Rumana". In a recent visit to the Aeronautic Museum in Bucharest we could see the four-cylinder engine that was built under license from DeHavilland.

“IAR de cuatro cilindros”

-The engine is mutilated and without accessories. To its side there is another one that does have accessories.

“IAR-4, more complete”

-There is also a six-cylinder IAR-6-G1 that gave 180 CV, next to an original DeHavilland.

“IAR-6-G1 licenced Gipsy Six from DeHavilland”

-The IAR-6-G1 was a six-cylinder engine built under license by IAR, an identical copy of the Gipsy Six.

-In fact, at the Bucharest Museum there is an original DeHavilland engine next to it.

-Both are identified by their name on the crankcase top cover.

“An authentic Gipsy Six engine”

-Just behind it, we see the one built under license by IAR, the 6-G1.
